Title:
【発明の名称】エンジンのアイドリング回転数制御装置
Document Type and Number:
Japanese Patent JP2832301

B2
Abstract:
A feedback control system has a comparing section to compare idling engine speed with a wide dead zone and a narrow dead zone. The wide dead zone has a predetermined width with respect to a desired idle speed. The narrow dead zone width is narrower than the wide dead zone width. When the idling speed is out of the wide dead zone, the system selects the narrow dead zone for rapid convergence of the idling speed. When the idling speed is within the narrow dead zone, the system selects the wide dead zone to prevent hunting.
